摘要： In some embodiments, initial feedback indicating threshold characteristics (under which a user sees initial stimuli presented on a user interface) may be provided to a prediction model, and a set of predicted characteristics (for a set of locations of the user interface) and a set of confidence scores associated with the set of locations may be obtained via the prediction model. Based on the set of confidence scores, one or more locations may be selected to be tested during a visual test presentation. As an example, the locations may be selected over one or more other locations of the set of locations based on the set of confidence scores. Based on predicted characteristics associated with the selected locations, stimuli may be presented at the selected locations during the visual test presentation. Visual defect information for the user may be generated based on feedback from the visual test presentation.

摘要： Ophthalmic imaging systems and related methods provide pseudo feedback to aid a user in aligning the user's eye with an optical axis of the imaging system. An ophthalmic imaging system includes an ophthalmic imaging device having an optical axis, a display device, an eye camera, and a control unit. The display device displays a fixation target viewable by the user. The eye camera images the eye to generate eye image data. The control unit processes the eye image data to determine a position of the eye relative to the optical axis, processes the position of the eye relative to the optical axis to generate a pseudo position of the eye relative to the optical axis, and causes the display device to display an indication that provides feedback to the user that the eye is located at the pseudo position of the eye relative to the optical axis.

摘要： Methods, apparatus, and systems for performing an ophthalmic diagnostic test are disclosed. In one aspect, a head-wearable device for administering an ophthalmic test to a subject can comprise a head-wearable frame for mounting the device onto the subject's head, and a light seal configured for coupling to the frame so as to isolate at least one eye of the subject from ambient light when the device is worn by the subject.

摘要： Methods and systems for assessing a visual field of a person are provided. Information can be presented to a person undergoing a visual field testing in a manner that utilizes the person's natural tendency to look at an object that is displayed so that it attracts the person's attention. A fixation target can be displayed on a display viewed by a user. Once it is determined that the user has viewed the fixation target and the person's eye(s) location is determined, a test target is displayed on the display in a location corresponding to a location on the user's visual field. The test target is determined to be either detected or missed based on user input acquired as the user is viewing the display.

摘要： The invention relates to a method for obtaining a visual field map of an observer, particularly a perimetry method, wherein a plurality of test locations in front of the observer is provided, at each test location of a subset of said plurality a respective perceived sensitivity threshold is measured, wherein at least one light signal is provided at the respective test location, and wherein it is monitored whether said observer observes said at least one light signal, and wherein for each test location a respective estimate of the perceived sensitivity threshold is derived from the previously measured perceived sensitivity thresholds of said subset, and wherein said light signal is provided at a light intensity value derived from the estimate of the perceived sensitivity threshold of said respective test location.

摘要： The invention relates to a method for determining the likelihood of being at or beyond a certain rate and/or risk of visual field progression (VFP) of a user, comprising the following steps: an installing step (S100) comprising placing or implanting a continuous-wear sensor on or in an eye of a user; a measuring step (S101) comprising measuring ocular biomechanical properties (OBP) through the continuous-wear sensor placed on or implanted in the eye, with said measurement comprising repeated data capture at regular time intervals; a recording step (S102) comprising recording the user's ocular biomechanical properties in the form of at least one OBP time series plot in a recorder; a processing step (S103) wherein at least one of a plurality of OBP parameters are extracted from the at least one recorded OBP time series plot; a calculation step (S104) wherein the at least one of a plurality of OBP parameters are associated to VFP; a determining step (S105) wherein one determines whether the visual field progression is at or beyond a certain VFP threshold and/or the probability that the said visual field progression is comprised within a specific range; a predicting step (S106) wherein based on the determined VFP, one predicts the probability of a patient to develop a glaucoma, and a judging step (S107) for judging of a specific medical treatment based on the above prediction result.
